I see this error when booting my Flame with 2 SIMs inside:

04-17 18:36:19.900 19293 19293 W GeckoConsole: [JavaScript Error: "TypeError: slot.simCard.iccInfo is null" {file: "app://" line: 60}]

I don't know if there is any user-facing issue but at least this prevents subsequent code from running, which could be bad.
Arthur, any ideas?

Although I'm not able to reproduce it but it seems a racing. The iccinfo may not ready upon the starting up. I'll provide a patch later.

Alive, in this patch I added an additional handler on simslot-iccinfochange so that we can run the operator variant handler at the correct time. A check on iccInfo was also added. The logic of the checks and operator variant handler creation was moved to a separate function to avoid code duplication. Would you mind take a look at it when you get a chance? Thanks.

Julien, could you try whether the patch fixes the issue? Thanks.

Actually it's difficult to say, I don't see this everytime I boot the Flame (actually quite rarely). So I can't check for sure this fixes the issue (but I think it does).

Also I'm not sure how I could check that everything still works as expected, but I applied the patch and used the phone simply and it seems to work fine. I'll assume alive knows better about it :)

Indeed, it is a racing and might be difficult to reproduce. Let's commit the code first and reopen the bug if it occurs again.

[Approval Request Comment]
[Bug caused by] (feature/regressing bug #): N/A
[User impact] if declined: The possibility is low but once happened the operator variant settings may not be applied correctly.
[Testing completed]: Unit test added. Testing on the device ok but note that the the original reproduce rate is pretty low.  
[Risk to taking this patch] (and alternatives if risky): Low. It fixes a racing by listening to events from gecko.
[String changes made]: None
